Note 2: The LT3571E is guaranteed to meet specified performance from

0°C to 125°C junction temperature. Specifications over the –40°C to

125°C operating junction temperature range are assured by design,

characterization and correlation with statistical process controls. The

LT3571I is guaranteed to meet performance specifications over the –40°C

to 125°C operating junction temperature range.
